The Australian Golf Course Superintendents' Association provide a great service by making so many of the presentations from their annual conference available for online viewing. 

At the 27^th Australian Turfgrass Conference in Adelaide, I gave presentations about turfgrass nutrient requirements, about grass selection, and about managing turf in microclimates.

The presentation on nutrient requirements highlighted the importance of nitrogen in comparison to the other mineral elements and explained why, when we think about fertilizer, the most important thing for a turfgrass manager to consider is how much nitrogen is being supplied to the plant. The topics discussed in this presentation are related to the MLSN guidelines developed with PACE Turf and are similar to those explained in the seven page handout Understanding Turfgrass Nutrient Requirements.
